Earlier this month the 57-year-old appeared on Sirius XM Radio where she called Boyle a "lovely lady" who had been hit by "the ugly stick".
In her apology, the America's Got Talent judge said: "Susan Boyle is a lovely gracious woman and I took advantage of that by poking fun at her. I would never want to be responsible for hurting Susan and I must apologise for getting a cheap laugh at her expense."
